Context Before
Let’s now go through a refresher on the LPU architecture to see how Groq’s LPU complements Nvidia’s GPU. For more details see our original Groq piece. ↗ The premise from that piece remains unchanged: the standalone Groq LPU system is not economical for serving tokens at scale, but it can serve tokens very quickly which can demand a large market premium. This is the premise behind how LPU fits into a disaggregated decode system.

Context After
Concretely, LPU architecture has VXM slices for vector operations, MEM slices for loading/storing data, SXM slices for tensor shape manipulation, and MXM slices for performing matrix multiplication. Spatially, the slices are laid out horizontally, allowing the data to stream horizontally. Within a slice, instructions are pumped vertically across units. Conceptually, LPU resembles a systolic array that pumps instructions vertically and data horizontally.
